FIG. 3. — Sticker microfluidics can be assembled by hand in minutes. (a) Microfluidic stickers are comprised of a fluidic interface of PDMS (Sylgard 184) with multiple laser cut tape layers. (b) Each tape layer has two backing layers that must be removed during the assembly process. (c) Upon the removal of the first backing layer, tape layer 1 can then be gently pressed onto the PDMS fluidic interface. (d) The second and final backing layer is removed from tape layer 1 with tweezers, and the first backing of tape layer 2 is removed to prepare for adhesion. (e) Tape layer 2 is applied with similar gentle pressure onto tape layer 2. (f) The final backing is removed from tape layer 2 with tweezers. (g) The microfluidic mixer manufacturing is done and ready to be applied to the user's surface of choice.
